Seems like most players allow you to import your folders without resorting all of your music.

Example: Deadmau5 folder on my computer has everything that's Deadmau5, but these also include songs that feature another artist. Jaangle will than take each featured artist and give them their own line item in the player as follows:

Yeap thats a must. All compilation albums are put all over the place. I also dont like the "online service","Preview similar - Purchase info" stuff that dont work and i think they should be removed to become even lighter. But the thing is that Alex is working on a new player so the resources to code/test/bugfix something that seems to become legacy i dont think are well-spent.
